Specification of Letters Patent.

Patented June 9, 1908.

Application filed November 20, 1907. Serial No. 403,105.

T o all whom 'it 'may concern:

Be it known that I, JOsEPH ScnnNox HOOKER Lovnrr, of the city ofTrenton, in the county of Mercer, in the State of New Jersey, one of theUnited States of America, have invented certain new and usefulTmprovements in Feeding Mechanism for Hose- Making Machines, of whichthe following is the specification.

My invention relates to improvements in feeding mechanism for hosemaking machines, and the object of the invention is to devise a machinewhich will quickly and automatically deliver the canvas, cut andprepared by the cutting machine, ydirectly to the hose making machineand also attach the rubber strip forming the outside jacket of the hoseto the canvas body preparatory to its being wound by the completingmachine and it consists essentially of a rectangular frame, T-shapedstandards secured in bearings to each end of the frame and capable ofvertical movement therein, mechanism actuated from the driving shaft ofthe cutting machine for imparting such vertical movement to the T-shapedstandards, rollers journaled at their end in the standard, supplementarybearing standards located at each end of the aforesaid frame, crossshafts journaled in the supplementary standards, pulleys mounted on thecross shafts intermediately of the rollers, belts extending between thepulleys at each end of the frame and located between the rollersjournaled in the main frame, mechanism for driving the belts from themain drive of the cutting machine, grooved wheels secured on pivotedarms in proximity to each end of the machine and means for adjusting theheight of such wheels as hereinafter more particularly described by thefollowing specification.

Figure 1 is a general perspective view of my machine attached to thedriving mechanism of a cutting machine. Eig. 2 is a plan view of mymachine. Fig. 3 is an enlarged cross section of my machine.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the main frame, rectangular in form.

A are vertical bearings located to the inside of the end bars of theframe A.

B are T-shaped standards the stem B of which are held in the bearings Ay andmthe cross heads B2 of which are provided with bearing notches B4.

B4 are a series of rollers extending longitudinally of the frame andhaving pintles extending from the end thereof1 which rest in the bearingnotches vB3.

O is a driving shaft, driven from a suitable source of power andjournaled iny bearing bracket O in the base of the frame A.

O2 is a pulley thereon and C3 is an endless cord or belt extendingaround the pulley C2 and around the grooved portions B5 of the rollersB4.

B6 is a rock shaft journaled in the brackets in the main frame A.

B7 is an arm secured to the rock shaft BG.

B8 are cams secured to the main driving shaft D of the cutting machineD.

B1 is a link pivotally connected at one end to the arm B7. The otherendof the link B9 is provided. with rollers B10 engaging with camgrooves formed in the inner faces of the cams B8. These grooves are ofany shape suitable for imparting a rocking movement to the arm B7through the link B.

B11 are cam arms secured to the -shaft BG and engaging the lower end ofthe stems B.

E, E are supplemental bearing standards. E2, E3 are cross shaftsjournaled in suitable bearings.

E4, E5 are series of pulleys located opposite the space between eachpair of rollers B4 at each end of the machine respectively.

E6 are endless belts extending around each pair of pulleys, E4 and E5,located between each pair of rollers B4.

The shaft E2 extends beyond its bearingv standards towards the cuttingmachine Dl and is provided with a bevel pinion E7.

E8 is a supplementary shaft journaled in bearing in the main frame ofthe cutting machine.

E9 is a bevel gear secured to the end of the shaft E8 and meshing withthe pinion E7 in the shaft E7.

E10 is a ratchet wheel scoured to the shaft ES.

E11 is'a rock arm swung On the shaft E8 and E12 isa pawl engaging withthe ratchet E10.

E13.V is a link pivoted to the rook arm E11 and provided with rollersE14 at its opposite end.

E15 is acam secured to the main driving E2 and F/ and the shaft E3 withits corresponding shaft F. The gears are proportioned so as to drive thewheels F2 in unison with the belts E11.

The arms F are provided with extensions F5 extending at right angles to,and opposite to the pivot points of the arms.

F6 is a lever and quadrant which are connected by links F7 to theextensions By this arrangement the height of the wheels c may beadjusted to suit various thicknesses of material.

Having described the principal parts involved in my invention, I shallbriefiy describe the operation of the same. The steel pole 2 on which isheld the rubber tube 3 forming the base of the hose is placed inposition in the grooves of the wheels F2. The canvas as it passes fromthe cutting machine, is drawn by the revolving rollers B1 into the tableA. The required width of material 4, (see Fig. 3) is fed into the tableand severed from the main body and the cam B8 operates. It will benoticed in referring to Fig. 3 of the drawing that the inner edge of thecanvas falls when cut from the main body onto rubber covered pole towhich it is suitably cemented. By the operation of the cam B2, the camarms B11 are rocked from beneath the stemsB of the T-standards B; Thestandards B and the rollers mounted thereon are depressed therebylowering the portion of 'canvas or other material su ported there byonto the belts EG. The bellfs are then revolved by means of the cams E13which rotate the shaft Es through the ratchet and pawl E9, the shaft E8being connected by the evel gears E7 and E2, to the shaft E2. The beltsE6 are revolved sufficiently by one movement of the ratchet and pawl Eto convey the canvas almost past the front of the cutting machine. Therear end of the canvas strip is thereby left in front of the cuttingmachine so that the next piece of canvas as it is fed from the machineoverlaps the one previously fed enabling the strips to be cementedtogether end to end. The rollers H press these end portions together asthe canvas is conveyed forwardly.

E are pulleys placed intermediately of the pulleys E5 and support thebelts E15 which serve to carry the canvas on to the hose making machine.

5 is the rubber jacket or outer cover of the of the canvas previously toits being fed forward by the conveyer belts. n The outer roller H forcesthe cemented portions of the jacket and canvas together.v

From this description it will be seen that l have devised a simple formof conveyer which will quickly and automatically feed the canvas fromthe cutting machine to the hose making machine.
